Painted Stones

Any decent terrain table needs rocks, right? I started by priming these plastic rocks in white, then covered them in Astrogranite, a technical paint that adds grainy texture. But I ran out of Astrogranite, so I had to figure out how to complete the unfinished stones. I solved the problem (I hope) by using metallic colours such as Leadbelcher and Balthazar Gold to the non-Astrogranite surfaces, hoping that these bits look like rich veins of ore. I experimented with non-metallic colours on some other stones, but I don't think these are quite as successful, so I might just cover them in Astrogranite when my replacement paints arrive.
